Chumma is a genus of African tangled nest spiders first described by Rudy Jocqué in 2001. They are small, three-clawed spiders with a strong dorsal scutum. They have no fovea, and the posterior and median spinnerets are reduced. The males of C. gastroperforata have two pairs of abdominal pockets that play a role in mating. This genus was initially placed in the family Chummidae, but the World Spider Catalog places it in Amaurobiidae. Species it contains nine species in South Africa and neighboring countries: Chumma bicolor Jocqué & Alderweireldt, 2018 – South Africa Chumma foliata Jocqué & Alderweireldt, 2018 – South Africa Chumma gastroperforata Jocqué, 2001 – South Africa Chumma inquieta Jocqué, 2001 (type) – South Africa Chumma interfluvialis Jocqué & Alderweireldt, 2018 – South Africa Chumma lesotho Jocqué & Alderweireldt, 2018 – Lesotho Chumma striata Jocqué & Alderweireldt, 2018 – South Africa Chumma subridens Jocqué & Alderweireldt, 2018 – South Africa Chumma tsitsikamma Jocqué & Alderweireldt, 2018 – South Africa References External links Jeremy Miller: Picture of a Chumma sp.
